Thank you!
Well, i'vee seen (and participated in) small initiatives like this and this very often. They are, by themselves, an example of what this platform is really capable of, if used for the greater good.
But there are a considerable big number of large, ambitious, creative and amazing projects going on that actually blow me away. These are just a couple of them:
The Writers Block : Being a writer myself, this one really hits home. This project is a combination of writer's workshop, crypto club and (soon) publishing house. Their webpage is here
Mining the Year 1918 : Man, this is so awesome. The First Steem-Powered University Course. They implement the use of steemit as part of the class! Later, they will use it to advance educational projects.
The Teardrops Smart Media Tokens : This is one of the best i've found. This guy, @surpassinggoogle , is an initiative by himself. And this is is his magnum opus. I literally don't want to spoil anything, please, GO READ IT if you find the time.
A lot of other projects are in development. Here is an epic list of some of the most important.
And this is only beginning. So, yeah, i'm excited and stuff. :)
